Vision may be our greatest sense, but within the next decade, 43 million Americans will lose some or all of their sight due to age-related diseases.
That's a 50 percent increase over current levels.
The American Academy of Ophthalmology marked World Sight Day this week by urging those over 40 to watch for early signs of cataracts, glaucoma, macular degeneration and diabetic retinopathy.
The society suggests getting a baseline screening at age 40 even for those with no signs or risk factors for eye disease. Based on that initial screening, an ophthamologist can suggest intervals for follow-up exams. Those who have known risk factors, such as diabetes or high blood pressure, should consult their doctor about how frequently they should be checked.
"Many eye diseases progress without any warning signs," said Dr.
Michael Brennan, president of the academy. "Gradual changes in vision often
go unnoticed but can have a devastating impact on your ability to function
independently."
Brennan said the earlier the problem is detected, "the better your chances
are of preserving precious vision."
About 314 million people worldwide are visually impaired, including 45 million who are blind. Almost two-thirds of those affected are women.
Vision is treated by three types of specialists: opticians, optometrists and ophthamologists. The ophthamologists are doctors who treat injuries and diseases, and can perform surgery.
